four anterior legs, and second, third and fourth joints of tarsi, apical margin of 

 first abdominal ; pale yellowish. Annulus of flagelluin ochreous, involving about 

 four joints, removed nearly oue-third of the length of flagellum from the apex. 

 Rest of flagellum nearly black. Part of coxse, all of femora, tibia; and tarsi of 

 four anterior pairs of limbs, nearly testaceous. Part of scape, greater part of 

 posterior limbs, and the abdomen, except black on apical margin of antipenulti- 

 mate and all of two apical segments of abdomen, ferruginous. Part of trochan- 

 ters, apex of tibiae, basal and apical segments of posterior legs more or less deep 

 fuscous to almost black.

Plesiognatlius tragi I is n. sp. — Front polished, dorsulum polished, 

 parapsidal grooves distinct. Mostly black, legs and a mark on abdomen pale. 



% Length 3 mm. Face bolow antennas hairy. Frout polished with a faint 

 indication of a median impressed line, the rest of the head apparently impunc- 

 tate, polished. Cheeks with fine, short pale pubescence. Dorsulum polished, 

 practically impunctate, the grooves strongly impressed, terminating before the 

 posterior margin. Mesopleura? indistinctly sculptured shining, the pleurae sep- 

 arated from the sterum by a rugulose impression, narrower and more distinct 

 posteriorly. Scutellum strongly convex. Metathorax areolated, not at all 

 angled, the areas roughened, slightly shining. The areola rather shining, toler- 

 ably well defined, the transverse carina separating the metanotum from the pos- 

 terior face distinct. The thorax almost entirely covered with pubescence much 

 like that on cheeks. Wings hyaline, stigma triangular pale brown, nervures 

 darker. Areolet, pentagonal, recurrent nervure received by the areolet a little 

 beyond the middle, the disco-cubital nervure and transverse medium nervure in 

 posterior wings not broken. Petiole almost as long as posterior femora, about 

 twice as broad at apex as at base, shining, longitudinally sculptured, second seg- 

 ment about twice as broad at apex as at base, and nearly as long as broad at apex, 

 third segment broader than long, nearly quadrate, the exposure of the rest of 

 the segments narrow. 



Black. Base of the wings and tegulae pale brown, the four anterior legs pale 

 almost testaceous, the trochanters and femora behind brown, posterior legs mostly 

 brown, second dorsal segment on posterior half medially, the apical border and 

 the third, the entire length medially rather tawny.

 N. M., Aug. 17, 1901 (H. Skinner). One male specimen. 



l*hyga«leuoii polita n. sp. — Clypeus with a few punctures, head, dorsu- 

 lum and abdomen polished, areola and petiolar area confluent. 



% Length 6 mm. Clypeus and mandibles with a few distinct punctures, face 

 distinctly convex, medially not polished like clypeus, and with separated fine 

 punctures, cheeks polished, sparsely punctured. Scape closely punctured, first 

 joint of flagellum a little longer than the second. Dorsulum polished, sparsely 

 punctured, closest anteriorly, parapsidal grooves starting strong, but short, rueta- 

 pleurse sculptured much like dorsulum, the groove deep and distinct. Areola 

 and petiolat areas confluent, bounded by a distinct carina, basally shining, apical ly
